Voyager 1 reached a distance of 135 AU (12.5 billion mi; 20.2 billion km) from the Sun on May 18, 2016. [4] On September 5, 2017, that had increased to about 139.64 AU (12.980 billion mi; 20.890 billion km) from the Sun, or just over 19 light-hours; at that time, Voyager 2 was 115.32 AU (10.720 billion mi; 17.252 billion km) from the Sun.

Voyager 1 completed the phase of termination shock in December 2004 at a distance of 94 AU, while Voyager 2 completed it in August 2007 at a distance of 84 AU. After entering into the heliosheath, the spacecraft were in an area that is dominated by the Sun's magnetic field and solar wind particles.
Voyager 1 is still active. In about 40,000 years the star Gliese 445 (AC +79 3888) and the Sun will fly past each other at a distance of 3.45 light-years, after being currently 17.6 light-years from each other, [8] with Voyager 1 coming as close as 1.6 light-years to Gliese 445 at that time.

Given Voyager 1’s immense distance from Earth, it takes a radio signal about 22.5 hours to reach the probe, and another 22.5 hours for a response signal from the spacecraft to reach Earth.
New Horizons encounters Pluto at a distance of 4.7 billion kilometres, and the communication takes 4 hours 25 minutes to reach Earth. 10 −3: 2.04 × 10 −3 ly: The most distant space probe, Voyager 1, was about 18 light-hours (130 au,19.4 billion km, 12.1 billion mi) away from the Earth as of October 2014.

The spacecraft launched in 1977 and is now 15 billion miles from Earth. It went silent in November. Scientists at JPL figured out how to get it talking again.
A long-distance fix. Voyager 1’s flight data system is responsible for collecting information from the spacecraft’s science instruments and bundling it with engineering data that reflects the ...
In September 2013, NASA announced that Voyager 1 had crossed the heliopause as of 25 August 2012. [37] This was at a distance of 121 AU (1.81 × 10 10 km) from the Sun. [38] Contrary to predictions, data from Voyager 1 indicates the magnetic field of the galaxy is aligned with the solar magnetic field. [39]
